Be sure to turn off and unplug the printer before accessing the interior of the printer for cleaning, 
maintenance, or troubleshooting. Accessing the interior of a live printer can result in electric shock.

Once a month, turn off the printer and check the AC power cord for the following:

■

The AC power cord is plugged firmly into the AC power outlet.

■

The plug is not excessively heated, rusted, or bent.

■

The plug and outlet are dust free.

■

The cord is not cracked or frayed.

■

If you notice any unusual conditions, call your dealer or Brother Customer Service for assistance.

When the printer is not used over an extended period of time, it is advisable to unplug the printer.

Switch off the printer before connecting the interface cable or options. Connecting the interface cable or 
options to a live printer can cause electric shock.

This printer may interfere with radio or television reception, causing flickering or distortion. This can be determined 
by turning the printer off and on. To correct interference, perform one or a combination of the following procedures:

■

Move the printer away from a TV and/or radio.

■

Reposition the printer, TV and/or radio.

■

If the printer, TV and/or radio are plugged in to the same AC power outlet/socket, unplug them, then plug 
them into different AC power outlets/sockets.

■

Reposition the TV and/or radio antennas and cables until the interference stops. For external antennas, 
consult your local electrician.

■

Use coaxial cables with radio and television antennas.

Operating Precautions

Do not place any liquid containers such as vases or coffee cups on the printer. Liquids spilt on the printer 
can cause a fire or electric shock.

Do not place any metal parts such as staples or clips on the printer. If metal or flammable materials get into 
the printer, they can short circuit internal components and cause a fire or electric shocks.

If debris (metal or liquid) gets into the printer, turn off and unplug the printer. After that, call your dealer or 
Brother Customer Service immediately. Operating a debris-contaminated printer can cause a fire or electric 
shock.

Never open or remove printer covers that are secured with screws unless specifically instructed to do so 
in this guide. High-voltage components can cause electric shocks.

Do not try to alter the printer's structure or modify any parts. Unauthorized modifications can cause fire.

This printer complies with the IEC60825 (Class 1) international laser standard. This means that the printer 
does not present any risk of injury to individuals from laser radiation. Various covers confine the laser 
radiation to the inside of the printer; hence, users cannot incur injury from the laser under normal operating 
conditions. Removing covers, unless instructed to do so in this guide, can cause injury from laser radiation.
